Code: # include <iostream> using namespace std ; class Polynomial { private : int *array ; int x ; public : Polynomial(int y=0 , int arr[]=0) { x = y ; array = new int [x+1] ; } void setPolynomial() ; void setPolynomial(int*) ; int getPolynomial() ; void operator = (const Polynomial& ) ; Polynomial operator * (const Polynomial& ) ; }; Polynomial Polynomial::operator * (const Polynomial& p) { x = p.x ; int* arr = new int [x+1]; for ( int i = 0 ; i < x+1 ; i++ ) { arr[i] = array[i] * p.array[i] ; } Polynomial result(x); result.setPolynomial(arr); return result; } int main () { int power ; char choice ; cout << "The Polynomial Function to the Power : " ; cin >> power ; int* poly1 ; Polynomial p1(power ,poly1); p1.setPolynomial() ; cout << "Enter Operator ( + , - , * , = , +=(1) , -=(2) , *=(3) ) : " ; cin >> choice ; if ( choice == '*') { int* poly2 ; Polynomial p2(power ,poly2); p2.setPolynomial(); Polynomial p3 ; p3 = p1 * p2 ; cout << endl ; p3.getPolynomial() ; } system("pause"); return 0 ; } excuse me i want help in the operator * it only multiply the cofficients but i want it to multiply in this form (4x2 – 4x – 7)(x + 3) = (4x2 – 4x – 7)(x) + (4x2 – 4x – 7)(3) = 4x2(x) – 4x(x) – 7(x) + 4x2(3) – 4x(3) – 7(3) = 4x3 – 4x2 – 7x + 12x2 – 12x – 21 = 4x3 – 4x2 + 12x2 – 7x – 12x – 21 = 4x3 + 8x2 – 19x – 21 can any one help me in this code plz
